BACKGROUND

This application describes the systems, apparatus, and methods for the reduction of drag in a spacecraft or missiles. The reduction of drag in spacecraft and missiles is desired as atmospheric friction will cause heat that can then cause a nosecone to fail. Clearly ways to reduce nosecone friction would benefit high speed missiles, allowing them to travel at higher speeds, and spacecraft, during the period of atmospheric reentry.

Also described are the details and means to transform a hypersonic stochastic vortex flux Z-plane singularity back into isentropic Y-plane mode by means of micro/planetary splines that reset the hypersonic stochastic vortex flux back into a supersonic isentropic front by means of contra rotating micro or planetary splines.

SUMMARY

The inventive subject matter is about a thermally reactive nosecone mounted on a projectile for achieving hypersonic transport comprising: an incipient shockwave, the incipient shockwave being transformed into an isentropic flux via a stochastic switch. A core component of the thermally reactive nosecone is a stochastic switch or a singularity, which is the consequence of isothermal compression and/or hypersonic liquefaction and/or regenerative cooling and/or Joule-Thomson throttling and complex cryogenic Carnot refrigeration triggered via sudden expansion and/or a porous plug integrated into the discharge end of the thermally reactive nosecone whereby a linear continuum of the incipient shockwave is transformed into a gyrating perfectly random stochastic vortex/stagnation flux. In order to transform the stochastic vortex flux back into isentropic streamlines grooved isentropic splines in the inside the discharge nozzle and/or peripheral of the nosecone of the nozzle of the thermally reactive nosecone has been proposed in lieu of the porous plug triggering Joule-Thomson throttling and complex Carnot refrigeration simultaneously. In addition to Joule-Thomson throttling and complex Carnot refrigeration an extrinsic cryogenic resource may be applied to pre/sub cool the thermally reactive nosecone to supercharge the refrigeration power of the shockwave piercing stochastic switch. Liquid nitrogen and/or a liquid cryogenic propellant may be applied as the extrinsic cryogenic resource to supercharge the switching power of the shockwave thermally reactive shockwave piercing nosecone mounted on a projectile for achieving hypersonic transport. The thermally reactive nosecone may additionally be optimized for throttling and triggering complex Carnot refrigeration liquefaction of atmospheric oxygen to drive a rocket propulsion engine of a hypersonic transport.

In another embodiment of the invention the thermally reactive nosecone may be configured with an independent/freestanding isentropic hypersonic expansion nozzle to drive the thermally reactive nosecone as a cryogenic refrigeration apparatus wherein the isentropic hypersonic expansion nozzle of the thermally reactive nosecone is optimized to distill liquid helium. Liquid helium hydrogen in the range of 1-5% of helium may additionally be introduced into the isentropic expansion nozzle to boost the liquefaction capacity of liquid helium. The thermally reactive nosecone may be additionally configured as a micro personal and/or enterprise scaled freestanding thermally reactive nosecone to distill liquid helium directly distilled out of compressed helium by means of the addition of isentropic splines within an hypersonic expansion nozzle in addition to tanked liquid nitrogen to (1) precool and (2) refrigerate the expanded helium proximal to the saturation curve of helium at absolute zero.

In another embodiment the thermally reactive nosecone is coupled within the confinements of rocket missile and/or aerospace plane with a centripetal thrust augmentation nozzle whereby (1) the centripetal thrust augmentation nozzle is equipped with grooved isentropic splines that transform/switch the stochastic vortex flux back into isentropic streamlines and (2) whereby the grooved isentropic splines centripetal thrust augmentation nozzle is equipped with enumerated supersonic ram detonation propulsive means in addition to grooved isentropic splines in isolation.

The inventive subject matter also comprises a system, apparatus and methods for a reduction of drag in a missile using a vortex tube as well as augmenting the thrust of a centripetal nozzle system with micro planetary splines.

In an embodiment is illustrated a method for reducing drag at hypersonic speed that includes the steps of mounting a liquefaction nosecone on the forward portion of a projectile; where the projectile is either a missile or spacecraft.

In another embodiment is described a method for reducing drag at hypersonic speed also having the steps of drawing an atmosphere external to the liquefaction nose cone an intake aperture or a discharge shaft.

In yet another embodiment is presented the details of a supersonic isentropic splines switching the stochastic hypersonic flux from the Z-plane back into the Y-plane to (1) maximize regenerative cooling of the shockwave piercing nosecone and (2) maximizing propulsive thrust augmentation of the stochastic or inversed centripetal supersonic ram detonation nozzle system.

This specification is not limited to a single embodiment, rather the methods and systems presented should be construed broadly and further incorporate the material presented in the drawings.

In an embodiment, FIG. 10 depicts a planetary splines gear transmission system 1000, wherein 1008/1009/1010 represent the outer/inner shell and the central shaft respectively and 1015 representing the contrarotating spline vortex flux. The sum of the splines induced micro/inversed vortices YY=power of the incipient/shafted vortex.

In a sudden expansion in a duct or nozzle system, the splines constitute a sudden/grooved expansion in a supersonic expansion nozzle whereby (1) micro contra rotating vortex streams are spawned via sudden expansion which minors the master vortex flux succinctly (2) the sum total of the micro/spline vortices equals the incipient master/mother vortex flux (3) the micro/spline flux negates the incipient master/mother vortex, the incipient master/mother vortex flux is spatially trans formed/reincarnated into supersonic isentropic streamlines.

The supersonic splines isentropic switch functions as (1) supercharged Joule-Thomson refrigeration engine in the cryogenic zone and (2) supercharged thrust augmentation expansion nozzle with a centripetal supersonic ram detonation thrust augmentation propulsive nozzle.

In order to model the dynamics of the splines hypersonic/stochastic and supersonic/isentropic transformation computationally vector matrix power factor analogy in conformance with electrical power transmission is being applied whereby in a purist isentropic potential field the stagnation and velocity vectors are in perfectly alignment/symmetry. Given that in a perfect electrical/fluidic potential field the current/voltage and stagnation pressure/velocity are in perfect alignment the power factor [COS(Ø)] must be unity (i.e. cos(Ø)=1.0) both ways. However, in event of current/voltage lead/lag and velocity/stagnation pressure divergence the power factor will be smaller than unity (i.e. cos(Ø)<1). In order to enumerate actual (real time) splines power factor divergence actual. Cryogenic regression [−180C/−170C/−150C/−140C/−120C/23C] (M5 stagnation pressure) data sets has been employed that rendered cos(Ø)=0.41/0.35/0.32/0.31/0.30/0.27 [66/70/71/72/73/74deg] as to purist (isentropic) and cos(Ø)′=0.36/0.33/0.30/0.30/0.29/0.26 [69/71/72/73/73/75deg] as to purist stochastic/random transformation respectively.

With the power factor postulation in place backed up with and actual measured (M5) hypersonic/cryogenic stagnation transformation “regression” data, the splines isentropic transformation may be modeled by an isentropical expansion as follows: M=((Pr){circumflex over ( )}0.286−1)×5){circumflex over ( )}0.5 generally and Me=((Prixcos(Ø)′){circumflex over ( )}0.286−1)×5){circumflex over ( )}0.5specifically and (2)T2=T1×(1+0.2Me{circumflex over ( )}2){circumflex over ( )}−1consequently.

Applying the data cos(Ø)′=cos(Ø)×0.887, Me=[((150×0.41×0.887) {circumflex over ( )}0.286−1)×5]{circumflex over ( )}0.5=[(3.14−1)×5]{circumflex over ( )}0.5=[10.7]{circumflex over ( )}0.5=3.3. Conversely given Me=3.3, T2=93×(1+0.2×3.3{circumflex over ( )}2){circumflex over ( )}−1=93×(2.18){circumflex over ( )}−1=93/2.18=42.7K=−230.5C. Noteworthy is that although the exit Mach number Me=3.3 is 30% lower than the incipient isentropic front @M5, the Mach number impairment is minimal taking in account that (1) (regenerative/isothermal compression shockwave piercing utility and (2) turning the splines into a powerful refrigeration engine.
